Thank you for visiting our Stand at OI2010

2010-03-24T12:10:00.001Z

I would like to thank you for visiting our stand at OI2010. I hope that you found our past projects and high resolution mapping techniques interesting. To recap on what we offer we can provide the following services;

Charting Surveys;

We have a long track record in performing IHO Order 1A surveys worldwide. Either from our dedicated survey vessels or by installing our equipment onto clients vessels. It typically takes between 24 and 48 hours to mobilise a vessel and the equipment is air freighted from the UK.

Coastal Surveys

Our high resolution surveys of the coastal margins have been recognised as world leading. We use sophisticated techniques to ensure that the bathymetric data ties in with the land survey data. The result of this is a seamless 3D digital terrain model that can be used for planning and storm/erosion assessment.

High resolution pipeline and site surveys

We specialise in delivering innovative solutions. Our procedures for Out-Of-Straightness surveys in deepwater and our QC routines have been adopted by major oil and gas companies as the new standard.

Port & Harbour Surveys

NetSurvey can provide a service that is second to none in the survey industry for ports and harbour surveys. Our work on quay wall deformation and damage surveys is ground breaking. We are approaching land survey accuracy of +/- 3cm in x,y and z from a moving platform and can confirm the deflection angle to better than 0.05 degrees. These surveys can be performed at the same time as an IHO Special Order harbour & approaches survey.

Marine Habitat Survey

By using the latest backscatter processing techniques NetSurvey can deliver high resolution seabed mapping of not only the bathymetry but also to classify the seabed sediment too. The following images are taken from a recent survey of chalk reefs south of the Isle of Wight.

NetSurvey at OI2010

2010-03-15T12:28:00.001Z

We had an excellent week at OI2010 in London last week. The highly visual stand attracted a large number of visitors from Oil and Gas majors down to small survey companies. Visitors were particularly keen on our laser integration and also the very high standard of our work

Major Caris HIPS hotfix

2010-03-04T09:35:00.001Z

There was a major bug in a previous HIPS 7 hotfix release to do with sound velocity, in that it didn't apply it properly. Caris have recently released a fix for this and it should be downloaded by anyone using HIPS 7 and applying Sound velocity corrections to their data. The Caris text is as follows;

*** Important Notice - Hotfix 3 now available ***

Hotfix 3 for HIPS/SIPS 7.0.1 is now available for download via the Online Customer Service webpage (http://support.caris.com). This hotfix addresses the previously reported SVC issue reported in the February 23rd notice. Once this hotfix has been installed, it may be required that users re-run any SVC that had been previously carried out in HIPS/SIPS 7.0.1 (Hotfixes 1-2) with the aforementioned inputs and options. We apologize greatly for any inconveniences or confusion that this may have caused.

Isle of Wight Survey is completed

2010-03-02T09:18:00.001Z

Yesterday (1st March) NetSurvey successfully completed the Isle of Wight Survey. The data looks fantastic and Ben, Gaelle and the MMT team on Seabeam have done a fantastic job. Images will be posted shortly. In the meantime here is Ben and Jacob (Seabeam's skipper) hard a work.

Working with MMT on Triad

2010-02-18T15:48:00.001Z

This year to enhance the processing & reporting turnaround for the Maritime & Coastguard Agency contract that Marin Matteknik have held for the last 5 years and that NetSurvey have provided the QC and reporting for, one NetSurvey Cat A Surveyor will be onboard all the time. Some specific NetSurvey processing routines are being adopted by MMT to enhance the product, in particular the Applanix POS MMS methodology for vertical control.

JP Cheminade is on board at the moment and can be seen working hard with near faultless data by the looks of it!

NetSurvey performing Habitat Survey to South of Isle of Wight

2010-02-15T13:48:00.001Z

NetSurvey are currently surveying to the South of the Isle of Wight for Natural England. The survey is to look at the Chalk Reef Habitats and we are using the MMT survey vessel Seabeam.

Ben Thompson and Gaelle Granjard are the two NetSurvey hydrographic surveyors. MV Seabeam is MMTs 24/7 small vessel (17m). Joel, Christian and Christoffer from MMT are also on board.

You can follow Seabeam's movements in the web page below;

NetSurvey CHAS 2010 Presentation

2010-02-05T10:17:00.001Z

Here is the presentation that I gave at the Maritime & Coastguard Agency's CHAS 2010 seminar yesterday.

Great site for AIS information

2010-01-20T16:46:00.001Z

I found www.marinetraffic.com last week. This appears to be a worldwide AIS realtime site and was quite up to date, only about 2 minutes old. I checked this by looking at myself on the Red Funnel ferry to the Isle of Wight last week. The screen grab shows the Port of London vessel Yantlet heading home after surveying off Burnham-on-Crouch today.

Fledermaus now reads in MBSystem FBT files

2010-01-06T17:11:00.001Z

For anyone out there who uses the free mbsystem multibeam processing software (developed by Dave Caress at the Monterey Bay Aquarium Research Institute (MBARI)) and has also got Fledermaus version 7 then in the upcoming 7.1 release you can now take the mbsystem fbt files and clean them or grid them in Fledermaus. This will allow you to use the CUBE algorithm to speed up your processing. Once you have finished your data cleaning/processing in Fledermaus you can unload the changes back to the fbt files and use these within mbsystem or GMT as you do currently. The files seems to load really quickly and that is both for creating DTMs and also for creating the PFM data structure which Fledermaus uses to process the data.

Here are some screen captures showing the lines and a grid in 2D in DMagic and then the PFM loaded into Fledermaus. Lastly a point cloud view coloured by line in the 3DEditor where you can reject bad points.

NetSurvey Staff Dedication

2010-01-06T10:52:00.001Z

This is dedication to a company. 30 cms of snow, roads shut and Mark, Ian, Max and Paul walk the 2 miles from the house in Great Boughton to the office!

Winter Scene from our office

2009-12-22T10:47:00.001Z

Winter has been here for about a week now but today is really pretty. Apologies for the quality but it is from my iPhone rather than a camera. Who wants to work in a town!!

What does 100TB of storage look like

2009-12-22T10:38:00.001Z

We've just added in another 16TB of storage so I thought I'd upload a photo of our main storage farm. The Apple XRAIDs (the bottom ones) are configured directly to workstations via 4GB/sec fibre optic cables and the Promise Technology enclosures are connected via fibre optics to the Xserve which is in turn dual gigabyte bonded to the main gigabyte ethernet network around the office.

It make quite a bit of heat but isn't too noisy so it is actually heating part of the office at the moment. The thought of running an aircon when the outside temperature is -4 degs C was like throwing money away. We just need a better system to duct out the heat around the office more efficiently.

MapWindow GIS

2009-12-10T15:35:00.001Z

If you just want to calculate areas and do a bit of digitising then MapWindow GIS is great, mainly because it is free. There are also some nifty plugins to allow you to create shp files from csv and dxf files, plus image rubber banding. Check out www.mapwindow.org

Cornwall Survey Results

2009-12-08T14:37:00.001Z

I've just realised that we haven't put up any of the results from the Cornish Survey yet on the blog, so here is an image I made from the Fledermaus scene of our bathy data combined with the EA's topo LiDAR data around St Michael's Mount.

7125-SV mounting bracket in use.

2009-12-08T09:32:00.001Z

Mark and Andrew have been up in the Orkneys surveying for renewable energy firms the last two weeks. This was the first time we have had a chance to use the new RESON mounting bracket for our 7125-SVs. Apart from a few small design faults (bolt lengths, etc) it worked very well. As you can see from the photo the bracket is designed for both the 400 kHz and the 200kHz transmitters with just the 400 kHz shown. The receive array is broadband so it can listen in to both frequencies

NetSurvey and Port of London complete combined laser and multibeam survey of an LNG terminal

2009-12-07T16:59:00.001Z

Combining multibeam bathymetry and laser scanner data gives you the best of both worlds above and under the water. The best thing is that it is very simple to do an very cost effective. You can collect both at the same time or go for laser at low water and multibeam at highwater to get a bit of overlap. Other great applications are cliffs, bridges, beachfronts, basically anywhere you want seamless coastal zone data. Here's an image of one of the results.

NetSurvey to supply Quality Control personnel for BP AUV survey

2008-08-19T15:05:00.001+01:00

NetSurvey have been contracted by BP Angola to supply quality control personnel for a 3 month AUV survey in Block 31 Angola. This is the third time BP Angola have contracted NetSurvey. NetSurvey will use IVS3D Fledermaus software to identify problem areas of data and to process data for BP.

Cornish Survey almost finished

2008-08-19T13:17:00.002+01:00

The survey from Lizard Point around to Lands End is almost finished. The weather has been worse than last year, which is saying something, but Max, Rob and JP have done some sterling work, getting into areas which we never thought we would get in. For instance they collected 100% coverage data behind St Michael's Mount. The image is the survey coverage so far completed.

NetSurvey surveying at the extremes of the British Isles

2008-07-03T12:17:00.003+01:00

NetSurvey are currently surveying off Lands End and also up in the Shetland Isles.

The Lands End survey is for Channel Coastal Observatory and the Maritme & Coastguard Agency. The survey is from Lizard Point to Lands End and extends from Mean Low Water Neaps out to 1 kilometre. Rob Bertram and Max Fisher are the NetSurvey personnel involved. They are running a Kongsberg EM3002 dual system with an Applanix POS MV 320 on the vessel Remote Sensor. The picture attached is of the vessel surveying with St. Michael's Mount in the background.

The survey in the Shetlands is also for the Maritime & Coastguard Agency and is part of NetSurvey's ongoing multi-year contract on the ETV Anglian Sovereign. Paul Robertson and Andy Sinclair are the senior surveyors up there. Already our survey has uncovered a 6m rock pinnacle where it was supposed to be 60 m of water on the chart! We submit H102s to the UKHO when we find significant differences to the charts which are then broadcast as a Notice to Mariners.

NetSurvey complete Bermuda Shipping Lanes Survey

2008-06-24T16:46:00.003+01:00

Paul Robertson, Mark Bennett and Max Fisher completed a multibeam survey of all the shipping channels in Bermuda in three weeks. The Bermuda Marine & Ports Department contracted NetSurvey to perform the survey. We mobilised a RESON Seabat 8125 and an Applanix POS MV 320 onto one of the department's pilot vessels, the St David.

This image gives an overview of the area covered.

Sound of Harris and Heysham surveys completed

2008-03-18T10:48:00.002Z

Ping has completed the Sound of Harris survey and the combination of Triad and Ping 2 have completed Heysham. Heysham was started in 2007 and then re-commenced in February this year. The survey was extended to cover the edge of a wind farm area to check the bank's position.

Sound of Harris survey

2008-02-18T11:47:00.002Z

NetSurvey and Marin Matteknik are currently in the process of surveying part of the Sound of Harris for the Maritime & Coastguard Agency. So far the survey has gone well and the image shows the coverage up until a few days ago.

NetSurvey win 9 month contract with Saipem

2008-02-18T11:01:00.000Z

NetSurvey have been awarded a 9 month contract by Saipem subsiduary Sonsub. The contract is to supply specialist multibeam personnel and software to support Sonsub's operations on the Medgaz project. The project involves pre-lay surveys, construction support and as-laid survey.
